Drawing in BDKanvas is quite similar to many other drawing tools. Three different tools are available:
- Brush tool
- Line tool
- Image tool
Brush tool 
This is a free drawing tool that allows you to freely draw any shape that you want. The available options on the brush tab are:
- Line color: the color of the line.
- Line width: the width of the line in pixels. Take into account that this width is not zoom dependent, it will be maintained regardless of the zoom level that you have.
- Closed line: the beggining and the end of the line will be linked together.
- Filled: the line will be filled with the given color.
- Fill color: if filled is selected, this color will be used.
- Dashed line: the line will be drawn as a dashed line.
Line tool 
This tool can be used to draw straight lines. The available options on the line tab are:
- Line color: the color of the line.
- Line width: the width of the line in pixels. Take into account that this width is not zoom dependent, it will be maintained regardless of the zoom level that you have.
- Dashed line: the line will be drawn as a dashed line.
- Initial and/or final arrow: the edges of the line will be drawn as arrows.
Image tool 
This tool can be used to insert an image. Once clicked, the user will be able to select a file to insert it on the page. Take care, as big images may take some time to synchronize with other clients if connected to a server and the connection is slow.
You can also insert an image by copying/pasting it from other programs.
If you select the image, the image tab will allow you to check whether the aspect ratio must be maintained when scaling it.
